QUESTION 3
The diagram below shows the plan of a proposed restaurant. The restaurant has buildings on
each side, there is provision for staff car parking at the rear of the building, and there is a public
walkway at the front which is owned by the restaurant.
The floor of the restaurant is constructed of concrete and is raised 200mm above the paved car
park area. If required, internal chambers are to be confined within the ablution blocks.
Foul water is to discharge to the Territorial Authority sewer at the front of the building.
The storm water drainage system is to include surface water from the car parking area and
underground drainage for all downpipes (DP) terminating at the Territorial Authority storm 
water sewer.
Using your knowledge of the New Zealand Building Code Clause E1 and G13 AS2, draw and
label the foul water and storm water drainage systems. Include all pipe work, connections, fittings,
chambers, inspections and any other relevant factors for a complete drainage system.
